A breakaway group of Anglican parishioners has been dealt a deathblow in their legal battle over ownership of a Riverside church.

The Supreme Court of Canada has refused to grant St. Aidans parishioners leave to appeal, dismissing their case with costs.

The group of about 100 parishioners broke away from the Anglican Church of Canada in 2008 over the churchs acceptance of same-sex marriage and other disagreements over interpretations of Scripture. The group joined the Anglican Network in Canada and went to court over ownership of the church building on Wyandotte Street East.
